心理弹性在童年期虐待与中学生暴饮暴食间的中介作用

The mediating role of psychological resilience to childhood abuse and binge eating among middle school students

为探讨心理弹性在童年期虐待与暴饮暴食之间的中介作用,本研究对黑龙江省哈尔滨市3 453名初高中生的童年期虐待、暴饮暴食及心理弹性水平进行测评.使用SPSS PROCESS宏程序并结合Bootstrap方法共同探讨心理弹性的中介作用.中学生童年期至少经历过一种虐待类型的发生率为81.3%(2 807名),童年期虐待、心理弹性及暴饮暴食在性别、户籍及是否独生子女方面均存在差异,具有统计学意义(P<0.05).童年期虐待与暴饮暴食行为呈正相关,心理弹性与童年期虐待及暴饮暴食行为呈负相关.童年期虐待不仅可以直接正向预测青少年暴饮暴食行为,还可以通过心理弹性对青少年的暴饮暴食行为产生间接影响.

To explore the mediating role of psychological resilience to childhood abuse and binge eating. This study assessed the childhood abuse, binge eating and psychological resilience of 3 453 middle school students in Harbin city, Heilongjiang Province. SPSS PROCESS macro program, combined with Bootstrap method, was employed to explore the mediating effect of psychological resilience. The incidence of middle school students experiencing at least one type of abuse in their childhood was 81.3%(2 807/3 453). Childhood abuse, psychological resilience and binge eating were all significantly different in terms of gender, household registration and whether they were only child (all P values<0.05). There was a significant positive correlation between childhood abuse and binge eating. Psychological resilience was negatively associated with childhood abuse and binge eating. Childhood abuse could not only directly predict the binge eating behavior of adolescents, but also could indirectly affect it via psychological resilience.
